VIDEO BUFFER MANAGEMENT TECHNIQUE

The video data buffering apparatus and associated methods provide audio and video data buffering in a video processing device. Specifically, the system relates to the use of a circular buffer and linked list FIFO employed in a video processing system, wherein video data packets from multiple video streams are stored in a common buffer to compensate for transport packet jitter. The apparatus and methods enable the system to store multiple QAM video stream packets in a common memory buffer. Linked list FIFOS are generated to identify the packets and their location within the common memory buffer. The linked list information is used to transfer the data between the common memory buffer and a modulator.
